Abstract
The supercontinuum spectrum generated by femtosecond Ti:Sapphire laser in photonic crystal fiber (PCF) can be increased into the UV by using small core diameter PCF with zero dispersion wavelength (ZDW) shorter 600nm. SC is generated in the region 350 to 1200nm with modulation less than 10 dB and with maximum spectral intensity near 350- 450nm. It is further shown that spectral intensity in the UV spectral region can be increased by employing dualwavelength pumping using the second harmonic of Ti:Sapphire laser beam as a second pumping wavelength.
